okay, so I didn’t quite know how to word the title and hope the explanation makes more sense.
As you might know by looking at my other questions, I am in the middle of making a nixie clock, and while my brain works out a few electronic bits, I have turned my attention to the case that will go around it.
I am looking to do a wooden case, but wanted something a bit more exciting than just plan wood.
I saw these voltmeters on eBay.
https://www.ebay.ie/itm/AC-0-300V-R...Meter-Voltmeter-Gauge-Black-W9N5/332732902474
I think they would look good inserted into the front of the case, but I want the needle to move in a random pattern up and down the scale when the nixie bulbs are turned on.
However the scale reads from 1-300volts, and I won’t have 300volts (don’t want to have) that amount of voltage floating around.
So my question is, is there a way I can fool the voltmeter to believe it is getting up to 300v, and is there a circuit I can build that will give the affect that the nixie clock itself is using the voltage and that is why the needle is moving?
Or if I was to get one that only measured up to 5v, how can I make the needle move?
I would like the needle to ‘flicker’ around slowly, stay still of a few seconds, slowly rise and fall, etc.
Any ideas on how I can accomplish this, and what sort of circuit I would need to build?
The smaller the design the better.
Thanks again for the excellent brains this site has.
